Lesson Introduction
Welcome to Topic 4. Let's move on to sampling methods and techniques. I will cover the different types of sampling methods and
formulas for calculation of sample size for quantitative research. I will
explain the probability and non-probability sampling methods. In addition, I will
also cover the methods/formulas for calculating sample size.
There are 3 main learning outcomes you will need to achieve through this lesson, as shown below.
You will also spend approximately 3 hours on this lesson.
Completing this topic will enable you to:
i. Describe sampling, population, element, sampling unit, subject and sampling process
ii. Compare the probability and non-probability sampling techniques
iii. Calculate the sample size for a given research project
